A student developed acute polyneuropathy after contact with stinging nettles (Urtica ferox). This case highlights Urtica ferox

Area of Science:

  • Toxicology
  • Neurology
  • Botany

Background:

  • Urtica ferox, a species of stinging nettle, is known for its urticating hairs.
  • Polyneuropathy is a condition affecting peripheral nerves, often presenting with motor and sensory deficits.

Observation:

  • A 21-year-old student experienced rapid onset of symmetrical, motor-predominant polyneuropathy after walking through Urtica ferox.
  • Two accompanying individuals reported similar, though less severe, symptoms following exposure.

Findings:

  • Nerve conduction studies revealed significantly diminished compound muscle action potentials and extended distal motor latencies.
  • The symptoms resolved within several weeks, indicating a potentially reversible condition.

Implications:

  • Cutaneous exposure to Urtica ferox can induce acute polyneuropathy.
  • The stinging hairs of Urtica ferox likely contain an as-yet-unidentified neurotoxin responsible for these neurological effects.
